		<name>urn:ogc:def:method:WCS:1.1:2dSimpleGrid</name>
	</methodID>
	<remarks>Method for use by a Coordinate Conversion defining a simple 2D GridCRS in a 2D GridBaseCRS, where this grid is not rotated or skewed in this GridBaseCRS. </remarks>
	<methodFormula>The reverse direction (from the grid CRS to the GridBaseCRS) shall be as specified by the equations:
	BaseX = origin(1) + offsets(1) * GridX
	BaseY = origin(2) + offsets(2) * GridY
where 
	GridX, GridY are position coordinates in the grid 2D CRS
	BaseX, BaseY are position coordinates in the 2D base CRS
	origin(1), origin(2) are the two coordinates of the grid origin position in the 2D base CRS
	offsets(1) is the grid point offsets of the first grid axis in the 2D base CRS
	offsets(2) is the grid point offsets of the second grid axis in the 2D base CRS

The forward direction (from the GridBaseCRS to the GridCRS) equations are not included here. </methodFormula>

			<remarks>This parameter shall be encoded as a wcs:Offsets element, giving the grid offsets in the two grid axes, relative to the specified origin. This wcs:Offsets shall contain two values, the first value shall specify the grid offset for the first grid axis in the first GridBaseCRS axis, and the second value shall specify the grid offset for the second grid axis in the second GridBaseCRS axis. </remarks>
